The Weather Channel reports online:

After dropping record amounts of snow (just over a foot) in the Dallas Metroplex Thursday a vigorous storm is spreading a nasty taste of winter eastward along the I-20 corridor into early Saturday.

Already from Shreveport to the Mississippi-Alabama line, snowfall has been in the 3-to-8-inch range.

Heading eastward from south-central Alabama, through the Savannah River Valley, to southeast North Carolina, three to six inches of snow will be common before all is said and done. Snowfall could reach 2 to 4 inches as far north as the Atlanta metro and the rain could end as a few inches of snow in Mobile.

Original Post:
The National Service reported on Thursday, Feb. 11, that the storm moving eastward along the Gulf Coast set an all-time snowfall record for Dallas:

...RECORD DAILY MAXIMUM SNOWFALL FOR FEBRUARY 11TH SET AT DALLAS  
FORT WORTH... 

THROUGH 7 PM CDT...DALLAS FORT WORTH AIRPORT HAS RECORDED 7.9 INCHES 
OF SNOW.  THIS BREAKS THE GREATEST CALENDAR DAY SNOW ON RECORD. THE  
OLD RECORD IS 7.8 INCHES SET ON JANUARY 15...1964 AND JANUARY 14... 
1917. 

THIS ALSO BREAKS THE RECORD 24-HOUR SNOWFALL FOR FEBRUARY WHICH 
WAS 7.5 INCHES...SET ON FEBRUARY 17...1978 AND FEBRUARY 25...1924. 

OBVIOUSLY....THIS SHATTERS THE RECORD DAILY MAXIMUM SNOWFALL FOR  
FEBRUARY 11TH...OF 1.4 INCHES WHICH WAS PREVIOUSLY SET IN 1988.
